Flowers and Spades, Dugan
This is an extremely rare pattern, sometimes referred to as Blossom and Spades. I show about a dozen of these 9- to 10-inch bowls in my database of auction sales over the last 17 years, all in peach opal. Most recent prices were $475 in 2009, $350 in 2012, and $200 in 2015. In 2016 an example sold for $160.

At the Karen Engel auction in 2017, an ice cream shaped bowl in purple sold for $6,500.

Small berry bowls are said to exist

Hartung Book Five: Flowers and Spades

In 2004, Bill Curtis sent me this photo of a Dugan Flowers and Spades bowl in peach opalescent that he had recently acquired. It's in a tricorner shape, the first I've seen. All the others I know of are ruffled.

In June, 2019, David Noyes sent me this photo of a peach opal tricorner bowl he had purchased from the John Rodgers collection that had sold at the ACGA auction. I don't know if it's the same as the one above, but there aren't many around. It is 9 1/2 inches wide at it widest part. The reported selling price was $600.
